5.4.2 Power-Up BIT Diagnostics
Power-up BIT Diagnostics perform di-
agnostics testing of the option system
every time the PC is powered-on. The
1640 Controller performs a basic
memory BIT test, and in the event of
an error, an audible tone (beep] will be
sounded through the system speaker.
If other circuitry on the board is not
functional, the system may either
hang or the monitor will not display
information. If a problem is encoun-
tered, run the Diagnostic Utilities.
(.5.4.3)
Prior to powering-on the PC, perform
the following hardware checks.
• The board is properly seated in an
expansion slot.
The board Address 1/0 Space switch
(SW 1 ) is set to a valid, non-
conflicting address.
• Monitor cable is properly connected.
• Monitor is powered-on.
